I was at the range yesterday sighting in one of my USPSA guns I had just installed adjustable sights on. I also took my two RIA 10mms. (A 5" FS Ultra and a 6" Pro Match)

Shooting off hand at 15, 25 and 50 yards, I was more accurate with my 5" Ultra than with the Pro Match. Even with the harsher recoil of the lighter 5" I was consistently more accurate with it than the heavier 6" Pro Match. I know off sand bags, the Pro Match is more accurate so I packed up my last 12 rounds and headed off to the rifle range.

Now, I haven't shot an open sighted handgun at 100 yards since 1987 when I was shooting silhouette with a T/C Contender. In the 80's I routinely hit targets as small as pop cans at 100 yards but now, almost 30 years later, I could barely make out the 9" foam plates someone left on the backstop. :'( >:(

With the 5" Ultra, I hit all around the plate.
The 6" Pro Match on the other hand...


I'm still gonna be shooting this gun off hand at shorter handgun ranges but I think I'm also gonna be shooting it more on the 100 yard range as well. ;D

Yes the 10mm is a fairly flat shooting round inside and out to 100 yards, beyond that it can drop more than 10"
Buffalo Bore has some trajectory charts shown;







if you study these charts and get to know your firearm and ammo it can show good hits at distance as you have seen from your pistol...

I have shot at milk jugs at 100 yards before.  I have about a 50% hit rate.  Or I used to when I made it to the range often.

Thanks guys.

That load was the Blue Dot recipe I got off here with the Xtreme 180 gr hollow point PLATED!  (This load has definitely become my "go to" load for the 10's)
For the first four shots I was using a "dead center" hold, then for the last two I was trying to guess the hold over like Elmer Kieth use to teach by raising the front sight above the rear and using my standard 6 O'clock hold. I guess the next time I go to the range, I'm just gonna have to take a screw driver and a note book and adjust the rear sight like I did in my silhouette days.  If I can figure out the sight dope, (and find a big enough target that I can see! LOL), 200 yards should be doable.

Using a rest, I can usually hit a grapefruit at 100yd with my P220 10mm, but only if it has a good contrast with the burm colorwise.

Really good fun doing that. Milk jug would be very fun too!

Milk jugs are fun. FROZEN milk jugs are really fun. Snow in July!

My results with Alliant e3 for my Tanflugio EAA Witness Compact Poly Carry were garbage with factory ammo we are speculating due to inconsistiency in powder load but mostly too slow burning powder. The comment about Blue Dot above is spot on as its about only a few steps slower still on the fast end at top. Red dot is faster & e3 fastest. We got incredible 2moa in 18mph gusts 100 yard short barrel 10mm 159gr results with e3 at 92-98% of red dot data but extremely careful precision charhe manual loading & winchester large / magnum primers. My suggestion is try some slower powders in steps. Be very  careful the heavier bullets with very fast powders have non linear pressure spikes.

I'm not sure what you're trying to say here. Maybe I missed it. Comparing 10mm Auto loads with e3 and Red Dot in the same discussion as Blue Dot makes as much sense as comparing gasoline octane rating results in your Gremlin and Z06. Uber-fast vs. mid-range magnum powders require a completely different process, and will not compare in results. Fast burn rate powders have their place, but nowhere near the discussion with slow(er) burn rate magnum powders, which includes Blue Dot. There are few powders faster than e3, and few (suitable) powders slower than Blue Dot, with dozens in between. Red Dot is very slightly less-fast than e3. 100 meter accuracy using bullets with the BC of a brick in 18 MPH gusts is like throwing said bricks, anyway. If you were able to achieve 2 MOA with any consistency, you are luckier than me. If I were able to make two consecutive shots, I would quit right then, and win the internet for the day.

20 MOA @ 200 yds? Or 2 MOA @ 20 yds? Sure.

By jove, you might be on to something there. Guess what just went into the big chest freezer for this weekend's range time.  ;D

For those who do not understand english. 20 rounds into clay 2" targets @ 100 yards= 2MOA.

Thanks for clarifying.  I think there were a bunch of us that didn't get your meaning the first time around.

My Engrish is fine, just not "clarified". "2 inch target @ 100 yds" is crystal clear.... Still trying to wrap my head around "2 MOA @ 100 yds, X20, for 92-98% in 18 MPH gusts with subsonic 159 gr. projectiles, from a compact pistol". His/her Military Optical Adjustment appears more effective than any I've seen.
